This study aimed to compare the radiologic results between closed nailing without bone graft (BG) and open nailing with BG for subtrochanteric nonunion and to determine when open BG should be considered.
In this retrospective study, we investigated the patients who underwent surgical intervention for subtrochanteric nonunion between January 2008 and March 2018 in two institutions. The cases with infection, large bone defect, pathologic fracture, open fracture, previous surgery using plate, and follow-up less than 1 year were excluded. We compared the demographic details and radiologic results between patients who underwent the open procedure with BG (BG group) and the closed procedure without BG (non-BG group) as a historical control, and risk factors for the failure of revision surgery were evaluated.

Removal of previous implant and re-alignment and re-fixation using intramedullary nail with (bone graft group) / without (non bone graft group) open bone graft

bony union
Union was defined as painless full weight bearing with the absence of fracture line or bridging callus across at least three cortices on the AP and lateral views.
Time frame: The time when bone union was achieved after surgery
risk factors for nonunion
Determining when open procedure with bone graft should be considered by analyzing risk factors for nonunion.
Time frame: One year after surgery
